FLUID CONTROLLER Filed March 5, 1929 2 Sheets-Sheet 2 'ntofa Patented May 6, 1930 PATENT OFFICE RICHARD T. ROYE, OF HOUSTON, TEXAS FLUID CONTROLLER Application led March 5,

This invention relates to new and useful improvements in a fiuid controller.

One object of the invention is to provide a Huid controller of novel design specially designed to be incorporated into and to form a part of a flow line leading from a well and intended to restrict and control the flow of fluid through said line. In producing oil when a well is brought in it is sometimes necessary to restrict the flow of oil, particularly when the oil is flowing under strong pressure. The reason for restricting the flow of oil is well known to those familiar with the art of oil production and need not be stated in detail. The controller herein de scribed has been designed for that purpose.

Another object of the invention is to provide a device of the character described in which the means for restricting the flow of oil are movable, preferably rotatable, so that the friction of the fluid and the gritty substances therein against said controlling means will be reduced to the end that said controlling means will be, in a large measure, relieved of friction and will not be readily worn away thereby and the fluid channel through the controller thus enlarged to a greater capacity than desired.

A still further feature of the invention resides in the provision, in a fluid controller, of adjustable controlling means for restricting the fluid channel through the controller to the end that said channel may be enlarged i and restricted as desired.

With the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts an example of which is given in this specication and illustrated in the accompanying drawing wherein Figure 1 shows a longitudinal, sectional view through the controller.

Figure 2 shows an inside view of a section or" the controller showing the controlling means therein.

Figure 3 shows a side elevation thereof.

two flow lines leading therefrom one of which is equipped with said controller.

Referrin now more particularly to the drawing w ierein like numerals of reference designate similar parts in each of the figures the numeral 1 designates the well casing to the upper end of which the casing head 2 is connected and leading from said head there are the two ow lines 3, 3 each being equipped with a gate valve 4 and incorporated into each flow line there is a fluid controller designed to control the flow of fluid therethrough. Unless so controlled when the fluid is iowing under strong pressure it will often cause the collapse of the screen down in the well or the sand in the fiuid will soon erode and destroy said screen.

Each controller embodies a housing, designated generally by the numeral 5 composed of two sections 6, 6 whose inner facing sides are flat so that the sections may be fitted closely together as shown in Figures 1 and 4c and v the ends 7, 7 of the housing are reduced and outwardly threaded to receive the collars 8, 8 by means of which the sections are held securely together and by means of which the controller is also incorporated into the line 3. The housing has the fluid conduit 9 extending therethrough axially from end to end through which the oil flows and the facing or abutting sides of the sections 6 have the pairs of registering recesses 10, l0,`one pair on each side of the conduit 9, provided to receive the oppositely disposed rollers 1l, 11 which are mounted on the pins l2, 12. The periphery of each roller is exposed to the fluid flowing through the conduit 9 and said rollers are rotated by said fluid and thus yield to the fiuid and tothe grit therein and are therefore not so liable to be worn away by the passage of gritty fluid between them. Between the rollers 11 are the oppositely disposed rollers which are mounted in the cavity 11i of the housing, said cavity extending transverse ly through said housing and being closed by `the plates 15, 16 bolted to the housing. Each roller 13 is mounted to rotate on a spindlel the ends of said spindle being fixed in the yolres as 18 and 18. The yokes 18 of each roller 13 are mounted on the transvepse Ashafts 19 which have end bearings in theV respective plates 1 5 and 16. The ends of the shafts 19 are extended beyond the plate 15, and have the spur gears 20,20 fixed thereon and in mesh with the spur gear 21 rotatably mounted on the plate 15 and having the outside nut 22 attached thereto to receive asock'et wrench by means of which said gear 21 may be turned.

. It is to be noted that ,each shaft 19 has threaded connections with the corresponding yokes 18 said threads being oppositelylpit'ched so that when the gear21 is turned in one direction it will operate through the *gears j2O to enlarge theconduit 9 between sail.V rollers and when thegear 21Vis turnedinthe-other directionthe rollers 13 will be moved-in position to restrict said conduit.

vIt is to be noted Vthat the rollers 13 t snugly betweenfthe rollers Vllas shown in Figure L1.
